What is a theodolite?
A theodolite is a Surveyor's measuring instrument that began to
take its present form in the 17th century. In the work, 'The
Surveyor in Foure Books' by Aaron Rathborne (London, 1616) an
elaborate drawing of a theodolite can be seen on the front piece.
These were used as early surveying tools, and were extremely
acurate. Thomas Jefferson used such an instrument during his time
as a surveyor. Later versions are also known as "Dumpy Theodolite",
while 20th century versions use extremely fine optics, or lasers.
The tool in it's present,modern versions is indespensible as a
surveying/mapping tool. Wala lang...Kervin to of BSCE 3-1
Theodolites- pronounced as it is spelled, are surveying instruments
of high precision and accuracy. They are a more sophisticated form
of what is usually called a transit. The Theodolite is always
operated from a tripod and has Base (circular) and Cylindrical
levels on the instrument to keep it level. The name is thought to
derive from the Greek- approximately ( The Eye of God). Modern
engineering, building and bridge construction, etc, even mining,
could not function without the theodolite and the more modern
derivatives using electronic devices and GPS. ( progress in full
swing, as with Cameras and electronic measurement of parameters, as
with modern non-digital Nikons.) By the way Nikon makes
theodolites. One of the best historically and by no means an
obsolete instrument was/is the Wilde-Zeiss theodolite which reached
its present form around l938. a common sight on Gotham building
sites. Their uses are many!
